b2 = fan contactor assembly 2

 

 

 

 

b3 = fan contactor assembly 3

 

 

 

 

b4 = fan contactor assembly 4

 

 

 

 

This item permits display of the fan stages. It also permits independent testing. In test mode the direction arrows permit

 

 

 

 

successive display of 0001, 0010, 0100 and 1000, so as to in turn force authorisation of each output.

Alarm command status/test

 

 

-

 

b1 = alarm circuit A

 

 

-

 

b2 = alarm circuit B

 

 

 

 

In test mode the direction arrows permit successive display of 01 and 10, so as to in turn force authorisation of each alarm

 

 

 

 

output.
